1. Introduction
GitLab is an open source project for warehouse management system. It uses Git as a code management tool and builds a web service on this basis.
GitLab has similar functions to Github, it is very easy to browse submitted versions and provides a file history library.
2. Installation
1. Obtain the installation package
wget https://packages.gitlab.com/gitlab/gitlab-ce/packages/ol/7/gitlab-ce-11.9.6-ce.0.el7.x86_64.rpm
2. Install dependency package
yum install curl policycoreutils openssh-server openssh-clients postfix
3. Install gitlab
yum localinstall gitlab-ce-11.9.6-ce.0.el7.x86_64.rpm
4. Configure gitlab
vim /etc/gitlab/gitlab.rb
#gitlab绑定本地IP地址或域名
external_url 'http://10.0.0.101'
#gitlab数据目录
git_data_dirs({ "default" => { "path" => "/data/gitlab-core" } })
#邮箱设置
gitlab_rails['smtp_enable'] = true
gitlab_rails['smtp_address'] = "smtp.exmail.qq.com"
gitlab_rails['smtp_port'] = 465
gitlab_rails['smtp_user_name'] = "[email protected]"
gitlab_rails['smtp_password'] = "123456"
gitlab_rails['smtp_authentication'] = "login"
gitlab_rails['smtp_enable_starttls_auto'] = true
gitlab_rails['smtp_tls'] = true
gitlab_rails['gitlab_email_from'] = '[email protected]'5. Start the service
# reload the configuration file
gitlab-ctl reconfigure
# start gitlab
gitlab-ctl start
6. Verify the mail
gitlab-rails console
Notify.test_email('recipient's mailbox','mail title','mail body'). deliver_now
7. Verify
Web: Access: 10.0.0.101
User: root
Password: rootpasswd 
3. Turn off automatic registration
# We turn off automatic registration, because our internal use does not require users to register themselves. Users can be assigned by operation and maintenance. 
4. Add keys. Do secret-free verification
1. Create the key
ssh-keygen -t rsa on the client side
2. Copy the public key
cat ~/.ssh/id_rsa.pub
3. Add the public key on gitlab. 
Note: You can pull code
five after saving , Backup and restore
1. Backup, default path: /var/opt/gitlab/backups
gitlab-rake gitlab:backup:create
2. Restore
gitlab-rake gitlab:backup:restore BACKUP=1610557313_2021_01_14_11.9.6
VI. Common commands #Create
git warehouse
git init
#Pull the code on gitlab
git clone git@linux-gitlab:web/web-demo.git #identity
authentication
git config --global user.email "[email protected]"
git config --global user.name "Your Name"
#Add the file to the warehouse for subsequent submissions
git add file.txt #Submit
the file to the warehouse
git commit -m "readme" #View
status
git status #View
the difference between the latest version in the workspace and the repository
git diff HEAD - readme.txt #Undo
all the modifications of the file in the work area
git checkout - file
#Undo the modifications in the temporary storage area and put it back in the work area
git reset HEAD <file> #Display
from the most recent to the most recent Far commit log
git log
git log --pretty=oneline #Return
to the previous version (HEAD means the current version, HEAD^ means the previous version, HEAD^^ means the previous version, and the upper 100 can be written as HEAD~100)
git reset --hard HEAD^ #Return
to the version before the return (all version IDs must be backed up before returning, otherwise you cannot go back to the future)
git reset --hard 1094a #Delete
the file from the repository
git rm file #Associate the
remote library
git remote add origin git@linux-gitlab:web/web-demo.git #Push
all the contents of the local library to the remote library
git push -u origin master #Pull
and integrate code from a warehouse or local branch
git pull #Create
a dev branch and switch
git checkout -b dev
or
git branch dev
git checkout dev
or
git switch -c dev # means to create and switch Branch
git switch master # means to switch directly to the existing master branch
# View the current branch
git branch
# Merge the dev branch to the current branch
git merge dev
# Add the --no-ff parameter to merge in normal mode, the history after the merge There are branches
git merge --no-ff -m "merge with no-ff" dev #Delete the
specified branch
git branch -d dev
# "Store" the current work site
git stash #View the
"Store" work site
git stash list #Restore the
"Storage" work site
git stash apply #After the restoration, the stash content is not deleted, use git stash drop to delete
git stash pop #Restore and delete the stash content at the same time #copy
a specific submission to the current Branch
